相场模拟研究AZ31B镁合金的动态再结晶
Insight into Dynamic Recrystallization of AZ31B Magnesium Alloys by Phase-Field Simulations
摘要
Abstract
Magnesium is widely used for materials science,aerospace,and military equipment.It is found that the mechanical property of magnesium under deformation loading is closely related to discontinuous dynamic recrystallization.In this work,we construct a dynamic recrystallization phenomenological model of magnesium alloy via phase-field methods.We choose AZ31B magnesium alloy as the research object and simulate grains and grain boundaries evolutions during dynamic recrystallization under 0.01-1.00 s-1 and 250-400 ℃.Iterative solving methods of stress-strain curves and recrystallization evolutions are improved by introducing plastic deformation energy to phase-field model.The simulation results show the volume fraction of recrystallization grains and the average grain size of samples increase with the rise of temperature and decrease of strain rates.关键词
